DISPENSING DEVICE FOR Cfi-RBONATED BEVERAGES.

Application filed December 15, 1919.

T 0 all whom it may concerm.

Be it known that I, CHARLES M. EARL, a citizen of the United Sta es, residing at Detroit, in the county of lVayne and State of lviilClligaIl, have invented a new and useful Dispensing Device for Carbonated Beverages, ot which the following is a specification.

This invention relates to devices for dispensing carbonated beverages, more particularly ginger ale, and is in the nature of an improvement upon the construction disclosed by Patent 1,297,333, issued March 18, 1919, to the applicant in this case.

In common with the present invention said prior construction comprises a gas separating or aerating chamber in a unitary relation with a valve controlling delivery from the beverage container to said chamber, the latter having an outlet for dispensing the beverage into serving receptacles, and the unit being adapted for direct connection to the beverage container, the beverage being sprayed upon the walls of the aerating chamber from a nozzle comprising a series of radial arms formed with jet openings arranged to produce rotation of the nozzle through the reaction of the discharge.

It is the object of the present improvement to surround the aerating chamber with a cooling chamber, which may be filled with cracked ice or otherwise cooled, to utilize the drainage from said cooling chamber to cool the pipe through which the beverage is delivered to the aerating chamber, and to provide within said chamber a series of battle members which will be encountered by such portion of the beverage as drops from the nozzle or is splashed from the walls of the aerating chamber.

A preferred embodiment of the invention is hereinafter described and is illustrated in the accompanying drawings, wherein,

Figure l is a view of the improved device in side elevation.

Fig. 2 is a vertical sectional view of the I same.

Fig. 3 is a cross-section through the aerating chamber.

In these views the reference character 1 designates a valve and 2 the casing thereof and 3 is a pipe depending from said casing for delivering a beverage from a container (not shown). It is to be understood that the beverage so delivered is impregnated with.

a carbonaceous gas, the major portion of Specification of Letters Patent.

which must be separated from the beverage to permit the pensed. Surinounting the valve casing 2 is an aerating or separating chamber, winch comprises a base i integral with said casing, a top 5, and a glass cylinder 6 clamped between said top and base by a means hereinafter described. The base i is formed with a di charge spout 7 leading from the bottom of the aerating chamber, which spout is controlled by a spring-closed plunger valve 8 operable by a push button 9 surmounting the valve stem.

The base i is engaged by the screwthreaded lower end of a stand pipe 10 which rises centrally within the aerating chamber, said end of the pipe connecting with the valve-controlled passage 11 of the casing 2. Said pipe terminates in the upper portion of the aerating chamber but has an integral solid extension 12 which projects through the top 5 and is screw-threaded for engage ment by a wing-nut 13 exteriorly bearing upon said top and clamping the same firmly upon the cylinder 6 and the latter upon the base 4. Discharge of the pipe 10 is effected through a rotative nozzle formed by a plurality of 'hollow arms 14- radiating from a collar 15 journaled on said pipe, and into which the inner ends of said arms are screwthreaded. Said arms communicate through an annular space 16 formed interiorly of the collar 15 and through a series of radial outlots 1'? formed in said pipe. Each of the arms 141: is formed with a row of jet orifices 18 at one side thereof, the location oi said orifices in the several arms corresponding so that reaction of the discharging jets upon the nozzle will induce rotation thereof.

Below said nozzle, in spaced relation to the same and to each other, there is mounted a series ofbaflle members each comprising a hub 19 and a plurality of arms 20 radiating from said hub and each carrying a number of small glass balls 20, said baiiie mem bers being held in their proper positions by spacers 21 sleeved upon the pipe 10. The uppermost of said spacers provides a lower thrust bearing for the nozzle, and the member 12 is formed with an annular shoulder 22 providing an upper thrust hearing. A vent passage 23 for the carbonaceous gases which are released within the aerating chamber is formed in the portion of the member 12 which extends through the top of said chamber, said passage having inlets same to be expeditiously dis- 24L ust beneath said top, and having outlets for the introduction of cracked ice or the 7 like into said cooling. chamber. A drainage passage. 29, leading from said chamber, 1s

formed in the base 4: and discharges into a pipe 30 which incloses the beverage supply pipe 3, the latter thus being. cooled to some extent byv the discharge from the cooling. chamber. 7

Discussing now the operation of the-described hivention when the valve 1 is openedthe beverage to be dispensed is delivered-from the pipe 3 throi h the casing 2. to the pipe 10, whence itescapes through the nozzle arms i l in the form of nunreroussmall jets which, as the nozzle rotates due to thereaction of thedischarge, are sprayed upon the transparent wall fi with substantialuniiformity. The liquid flows down said wallintheform of a thinvfilm; and in-this form the carbonaceous gas is readily liberated. A certain amount of thebeverage will, however drip from the nozzle arms 14,

and some will also be splashed from :thewalll 6. This is taken care oflby the described! bafl'le members; the arms-20 and balls 20 of which will be encountered by the falling;

drops and) transforming the latter either into a thin film or breaking them into fine particles, suc'has in either. event will readily, release the carbonaceous gas. Both valves 1 and 8 are opened while the beverage is being dispensed and in case any excess accumulates in the aerating chamberit may be stored there without becoming unduly warm owing to the provision of the cooling chamber 26. Said chamber permits a constant lowtemperature to be maintained in the aerating chamber, so that the beverage need suffer no rise in temperature while dis charging within said chamber, and the flow of drainage fromv the cooling chamber delivering a beverage to saiddnner: cylinder:

2. A- beve-rage dispensing device comprising-concentric cylinders a:base and atop, member between. which: said cylinders: are c-lamped the top I being apertu-redfor the introduction of cracked'ice-or' the like betweensaid cylinders and the base. being formed with a liquid discharge passage fromthe inner cylinder, and means for de liverlng avbeverage to said -1nner. cylinder.
